Air-Bearing Rotary Master Axis

The ABRT400 is the heart of Aerotech's µARC Angle and Rotary Device Calibration System. The ABRT400 is a large rotary air-bearing axis with nanometer-level error motion performance. This high-accuracy air-bearing master axis is constructed of steel to closely match the CTE of the µARC's surrounding granite structure. The air bearing is equipped with a non-influencing rotary union and slip ring to pass vacuum or air and electrical service to the device under test.

The ABRT400 can be used as the angular standard in high-accuracy measuring machines, x-ray diffraction, protein crystallography or high-precision machining applications.
